It is important to remember that very often there are no symptoms of colorectal cancer until the cancer is advanced. This is why it is important to begin and maintain a program of regular screening as recommended by your doctor. Common symptoms of colorectal cancer include:

Change in bowel habits

Blood, either bright red, or black and tarry, in the stool

Stools that are narrower than usual

Diarrhea, constipation, or feeling that the bowel does not empty completely
